Abstract:
TvSpan a joint venture project between Meridian Broadcasting TSMS and Taylor Nelson Sofres has been in operation since March 1996 with 750 Superpanel homes in the Meridian ITV region equipped with TV setmeters in addition to the scanning equipment they have to record the details of their purchases of fmcg products. Thus tvSpan provides a continuous measurement of both product purchasing and TV viewing from the same households - i.e. single source data and hence provides us with the means to address the issues of recency frequency and the duration of the effects of TV advertising.
